Annotation Type Threading

@Retention(value=RUNTIME)
 @Target(value={TYPE,METHOD})
public @interface Threading

Annotates a calls or method.

Annotated elements must follow these rules

• must be a public method
• name does not match an event handler
• must pass griffon.util.GriffonClassUtils.isPlainMethod() if it's a method

This annotation takes griffon.util.Threading.Policy as value, with Threading.Policy.OUTSIDE_UITHREAD being the default value.

The following snippet exemplifies the compactness of code when the annotation is applied

 import griffon.transform.Threading

 class Sample {
     @Threading
     void doSomethingOutside(String arg) {
         println "Outside $arg"
     }
     @Threading(Threading.Policy.INSIDE_UITHREAD_SYNC)
     void doSomethingInside(String arg) {
         println "Inside $arg"
     }
 }
 

The equivalent, non-annotated code is

 import griffon.core.threading.UIThreadManager

 class Sample {
     void doSomethingOutside(String arg) {
         UIThreadManager.instance.runOutsideUI {
             println "Outside $arg"
         }
     }
     void doSomethingInside(String arg) {
         UIThreadManager.instance.runInsideUISync {
             println "Inside $arg"
         }
     }
 }
